Crack-tip field at steady crack growth and vanishing linear strain-hardening.

Ståhle, P LU (1989) 7th International Conference on Fracture (ICF7) p.455-462
Abstract
A solution to the quasistatically propagating mode III crack in an elastic perfectly plastic solid is obtained as the limit solution for vanishingly small linear strain hardening. A point above or below the crack plane will experience, first, a centered fan slip line field followed at the angle ±32.8° ahead of the crack tip by elastic unloading and, finally, from the angle ±179.7° to the crack surfaces, plastic reloading occurs at a constant stress. The limit solution performs a discontinuity in the radial stress rate across the elastic plastic boundary at ±32.8° (6 refs.)
